Filed: 1995-08-04
Abstract: PURPOSE: To obtain a liquid crystal display device capable of a halftone display even though the liquid crystal display body having a storage effect is used by controlling the switching between two metastable states which is arbitrarily selectable by an impressing waveform with a driving voltage waveform. CONSTITUTION: One metastable state is generated and maintained in the period t03 provided in the frame having a period t0 regardless the state selected in a period t02 . Optical responses of pixels obtained by synchronizing respective signal electrode waveforms 302 to 305 with a scanning electrode waveform are optical response waveforms 306 to 309. Then, in the optical response of the waveform 309, the time quadrature value S0 in the period t0 having a transmissivity I and the time quadrature value S1 in a period t1 are set so as to become S0 :S1 =1:2 by adjusting a t0 /t03 ratio. Consequently, time quadratures of transmissivities in the period t0 +t1 are four patterns shown in waveforms 306 to 309 and become almost 0:1:2:3 and the assigning intensity levels having a luminance change in which continuity is present are made possible.

Title: Paper receiving device
Inventor: YAMASHITA HIROTAKA
IPC: B65H31/24
Filed: 1990-07-26
Abstract: PURPOSE:To smoothly perform a paper receiving process without causing a system down by receiving paper to the other paper receiving means, in which the paper can be received, when improper receiving is detected generated in the one paper receiving means. CONSTITUTION:A paper receiving unit 60 is controlled by first deciding whether an upper step jam flag is (1) or not. When a paper jam is generated in a passage for receiving paper to an upper step tray 70, possibility is provided with a paper rear end left in the vicinity of a switching pawl 67, and in this case, a paper receiving process is stopped because paper thereafter can not be received to a lower step tray 70a. When a jam is generated in a lower step, paper thereafter is received to the upper step tray 70 possible to circulate the paper. Accordingly, necessity for suspending a print process in a printer main unit 1 at each time of generating a jam is eliminated. Since the upper step tray 70 is shifted when paper circulation is switched to the upper step tray 70, paper, already received to the upper step tray 70, can be easily discriminated from paper received thereafter.

Abstract: PURPOSE:To safely perform desired operations by releasing an interlock according to the instruction of a releasing message shown on a display means to perform a manual operation. CONSTITUTION:In a CPU 33, an interlocked condition registered in advance on the internal table 99 of an interlock of an interlock control part 97 is compared with a mobile command from a manual operation module 87 to judge whether the command is executed or not. When the execution of the command is judged to be OK, the CPU 33 converts the mobile command into a mobile signal and sends it to axial control parts 37A-37C, an RLY module 59 to carry out manual operation for the carry-in-and-out device 3 of the work. When the execution of command is judged to be NO, the CPU 33 rejects the mobile command to display the interlocked condition and the releasing message on a CRT 47 through a controller 45. An operator releases the interlock immediately according to the indication to reopen the manual operation.

Title: Ultrasonic treatment apparatus
Inventor: TAKAYAMA SHUICHI
IPC: A61B17/22
Filed: 1987-08-13
Abstract: PURPOSE:To efficiently and certainly perform the destruction or emulsification treatment of a calculus or tissue by vibrating a vibration transmitting member not only in the before- and-behind directions along the axial direction thereof but also in a direction other than said direction, by providing electrodes for applying voltage to a piezoelectric element to at least the outer peripheral surface among the end surface and outer peripheral surface of the piezoelectric element. CONSTITUTION:The first and second vapor deposition films 3, 4 vapor-deposited on the piezoelectric element 2 of an ultrasonic vibrator 1 cover not only the end surface of the piezoelectric element 2 but also the outer peripheral surface thereof. Therefore, voltage is applied to the piezoelectric element 2 in the thickness direction almost vertical to the plate surface thereof and also applied between the end surface parts 3a, 4a and peripheral surface parts 3b, 4b of the vapor deposition films 3, 4 as shown by an arrow. That is, since voltage is also applied to the piezoelectric element 2 in the lateral direction not vertical to the plate surface thereof, ultrasonic vibration is generated in the piezoelectric element 2 in the same direction as the voltage applying direction. As a result, since the leading end of the vibration transmitting member 13 is vibrated not only in the before-and-behind directions but also in the lateral direction, the destruction or emulsification treatment of a calculus or tissue incapable of being well performed by the vibration in the before-and-behind direction can be well and certainly performed.
